PIPE JACKING THRUSTS AHEAD IN BATH SEWERS

The outfall section of Bath's sewerage interceptor system includes some 1.5 km of pipejacking in sizes from 900 mm to 1.65 M diameter. The advantages of the system, apart from the speed, cost and accuracy, include the lack of surface disruption and non-interference with traffic flows. It has been found that bolted segmented reinforced concrete thrust and reception pits are superior to those of conventional timbering. Several interesting and unusual applications are described in the article including the formation of an in situ concrete bend following jacking of 70 M lengths from opposite directions. Detailed geotechnical surveys are undertaken before each contract. Despite restrictions on environmental disturbances, it has been possible to work in two shifts up to 11 pm. /TRRL/
